Chapter 1 Product Overview
1.1 Product Introduction
E22-400T30S is a new generation of LoRa wireless module, based on
SEMTECH's SX1262 radio frequency chip wireless serial port module (UART),
with a variety of transmission methods, working in the (410.125 ~ 493.125MHz)
frequency band (default 433.125MHz), LoRa spread spectrum technology , TTL
level output, compatible with 3.3V and 5V IO port voltage.
E22-400T30S adopts a new generation of LoRa spread spectrum technology.
Compared with the traditional SX1278 solution, the SX1262 solution has a
longer transmission distance, faster speed, lower power consumption, and
smaller size; it supports air wake-up, wireless configuration, carrier monitoring, and automatic neutralization. Relay, communication
key and other functions, support subpackage length setting, and can provide customized development services.
1.2 Features
Based on SX1262, a new LoRa spread spectrum modulation technology is developed, which brings longer communication
distance and stronger anti-interference ability;
Support automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and multiple networks
run simultaneously in the same area;
Support users to set the communication key by themselves, and it cannot be read, which greatly improves the confidentiality of
user data;
Support LBT function, monitor the channel environment noise before sending, which can greatly improve the communication
success rate of the module in harsh environments;
Support RSSI signal strength indication function, used to evaluate signal quality, improve communication network, and measure
distance;
Support wireless parameter configuration, send command packets wirelessly, remotely configure or read wireless module
parameters;
Support wake-up over the air, that is, ultra-low power consumption function, suitable for battery-powered applications;
Support fixed-point transmission, broadcast transmission, channel monitoring;
Support deep sleep, the power consumption of the whole machine is about 2uA in this mode;
Support global license-free ISM 433MHz frequency band, support 470MHz meter reading frequency band;
The module has built-in PA+LNA, and the communication distance can reach 10km under ideal conditions;
The parameters are saved after power-off, and the module will work according to the set parameters after power-on;
Efficient watchdog design, once an exception occurs, the module will automatically restart and continue to work according to the
previous parameter settings;
Support data transmission rate of 0.3k
～
62.5kbps;
Support 3.3~5.5V power supply, and the best performance can be guaranteed if the power supply is greater than 5V;
Industrial-grade standard design, supporting long-term use at -40
～
+85℃;
Double antennas are optional (IPEX/stamp hole), which is convenient for users to develop secondary and facilitate integration.
